I have been reading up on doing calculus IN 3D USING PARAMETRIC EQUATIONS... that's totally sweet. What I mean is coming up with ridiculously complex (but neat looking) equations for x,y, and z of t and then finding their a) volumes and b) surfaces areas of revolution, as well as the lengths of curves (i.e in the back of the book it proves how to find the length of a cork screw, i.e like the railgun in quake2).
this stuff is totally sweet
